What you are looking for is proprietary. Disney doesn't even release their exact attendance figures. Why would they let someone audit their sales figures?
How are they reporting these things to shareholders?
There has to be some record of them making a presentation on "One Disney" at some point and that presentation would have necessarily included sales figures...showing how they were going to improve everything by going to "One Disney".
That could be compared to the current state of things and shareholder reporting. They must have to do this at some point for their merchandise divisions.
I just don't know how to find that.
